Chip carving knife from an old saw blade

I really like to use German chip carving knives. I experiment with making one of these out of a circular saw blade, first softening it to work it, then re-hardening it after I'm done.

Nice experimentation Matthias. As for the hardening & tempering, 1) heat the steel to cherry red (at this point it will be non-magnetic), 2) immediately quench vertically in oil, moving it up & down in the oil, 3) draw out the temper by baking it for a few hours at about 300-400 degrees F.

I make kitchen knives from old concrete circular saw blades. The steel is pretty good and they hold an edge well. My latest has become the wife's favorite.
I really enjoy your thrifty approach to problem solving. I really hate to see people throwing money at projects instead of thinking up solutions.

thank you for briefly explaining why/when to heat and cool quickly or slowly.

I've got an old-fashioned straight razor that needs a handle. I hadn't figured out how I was going to rivet it in there, but your softened-nail trick is perfect!

I've never seen a plasma cutter in action - that was amazing! Nice project too, even if I'll use an angle grinder to cut. Thanks.

Hello Matthias, and great video. I just discovered your videos here and watched a lot of them so far. I've always loved woodworking, and am starting up the hobby again; so I say thank you for the inspiration you give me. I always used hand tools mostly, but just built a large shed in the backyard and getting some good power tools and fixing it up real good. I got a nice table saw recently and already built the sled from your video. Excellent videos and a real joy to watch and learn from.

Another must watch video from Matthias.

I got into chip carving over the summer. Bought one knife from Woodcraft and then made a few more out of a circular saw blade. I just used a grinder to shape it though.

I'm seriously getting sick of all of these Harry's sponsorships on YouTube..

[SouthpawWorkshop]

This is definitely on my to-do list. Thanks Mathias!

Dont dispose of that "mistake" just grind it again on the other side and although it wont be the absolute perfect shape it will still work.

I made a chip carving knife several years ago, was going to learn chip carving, never did. I use the knife on almost every project that I do.

I've used a broken band saw blade to make a carving knife based off of one of those small Japanese type and it heat treated correctly and held an edge well (since that is what the original steel was designed to do). Also you could make literally hundreds of small knives from a broken band saw blade.

looks like a sturdier knife than the one I made from a hacksaw blade. Next time I decide a circular saw has had it, I'll have to remember this project. Though of course we don't all have plasma cutters...

Great project. I always wanted to try to make a carving knife.

0:40 notice the sparks that are formed when grinding high-carbon steel.

Lol, I read it as "cheap carving knife from an old saw blade"

[adrianwilliams]

I remember my father making carving knives from old hacksaw blades.

WHAT!!!? No dragons to fend off in CANADA!? ahhh the simple life...

hey bud i love your channel and i look up to you as a master wood craftsman but how did you get so creative with all those crazy things you build? did you go to architect school. your imagination to see such awesome projects is something else . keep up the good work
